CAR-AXLE LU BRICATO R.

SPECIFICATION forming part of Letters raten No. 371,258, dated october 11, las?.

Application sied March 23, ism. serial No. 232,055. (No model.)

To aZZ whom it may concern:

Be it known that I, RUDOLPH FAAs, a citizen of the United States of America, residing in the city of Chicago,county of Cook,and State of Illinois, have invented a new and useful Device and Improvement in Car-Axle Lubricators, of which the following is a specification.

This specification is tiled as an improvement on my former invention, for which Letters Patent No. 352,612 were issued November 16, 1886.

The usual method of lubricating car-axles is to fill the axle box with cotton waste and oil. This has been found unreliable andwasteful.

The objects of my invention are, first, economy in the use of the lubricant; second, to provide a continuously-lubricated axlejournal; third, to protect the lubricant from accumulations or deposits of sand, dust, or other foreign substances, and, fourth, to provide a substantially-constructed lubricator to withstand the constant wear from contact with the car-axle journal. I attain these objects by the mechanism illustrated in the accompanying drawings, to which- Figure l is a vertical cross-section of a caraxle box, showing the position of my device therein and its relation to the journal. Fig. 2 is a plan view ofthe device with a portion of the covers removed. Fig. 3 is a side elevation of the same. Fig. 4 is a sectional view on line 4 of Fig. 2. Fig. 5 is a sectional view on line 5, Fig. 4.

Similar letters refer to similar parts throughout the drawings.

Two metal bars,D D, wider at one end than the other, of a suitable length to be placed in a car-axle box, joined together by two bolts, d d, constitute the frame of my device. At the more elevated end of the frame D D so constructed an inclined slot or bearing, aa, about an inch or an inch and a half long, is made in each side of the metal frame, into which the journals of the roller E, Fig. 3, are placed. The frame D D and roller E are placed in position in the car-axle box B, Fig. l, and the roller E engages with the journal A. The constant motion of the roller thus obtained in the oil keeps the journal A continuously 5o lubricated. The slots or inclined bearings a a,

Fig. 3, incline in the direction opposite the journal A, thus allowing the roller E to bear against said journal A by its own gravity. The length of the slot permits a free play of the roller E, and relieves the roller from any severe pressure, friction, or concussion by sudden contact with the journal.

lA collar, o, is placed on or around thejournal a: of the roller E, in order to relieve and divide the friction and wear of the roller-journal zu, which adds very materially to the strength and durability of the roller and device. Itis removable, and may be replaced when desired.

The frame D D being connected by the bolts d d, which have one end permanently attached to one side of the frame, and secured to the other side by means ofthe nuts e e, I am enabled to place the device iu the axle-box B by disconnecting the frame and first taking the side having the bolts d d attached and pushing it back to the side of the j ournal-box the most distant. The roller is next inserted with its journal in the slot. The cover c is next placed in position, and, 1astly,the otherside of the frame and the bolts placed in position and fastened by the threaded nuts e e. The metal apron b is then placed at the head of the frame,4

one side of which, being concave, extends partly l over the roller E. Two rollers may be used, if desired, by simply placing another roller in a similar manner in the opposite end of the frame D D. By this method of journaling the axle of the roller in the inclined bearing or slot I secure greater protection and a larger degree of usefulness and service.

The metal cover c may be either loose and laid on the top of the frame D D, or it may have a flange on one side, which is perforated and one of the bolts d d, Fig. 5, passed through, thus firmly holding it in position.

The objects ofthe metal apron b and cover c are to exclude dust, sand, or other foreign substances from the oil in the journal-box and inclosed by the frame D D. I

The roller E is formed by the axle a: with the flanges z z, and around the spool thus formed 'is wound canvas, cloth, felt, or other porous substance. The journals of the axle are protected in their bearings by the collar o.

IOO

2. The combination of the roller E, made, as t described, of canvas, cloth, felt, or other porous material, with the frame D D, joined-together by the threaded bolts d d, nuts e e, the metal apron b, and cover c, to exclude dust, sand, or other foreign substances,substantially as described.

3. The combination of the inclined bearing 2ol or slot a, in which the journals of roller E operate, With the collar o and frame D D, joined by the threaded bolts d d and nuts e e, substantially as described.

4. A porous roller operating in an inclined 25 bearing or slot, by which the roller is brought in contact with the car-axle journal by :its own gravity, for thepurpose of continuously receiving, conveying, and serving the lubricant reposing in the bottoni of the car-axle box to the 3o journal of the car-axle.
